Nathan, I thought that this information may be helpful. I'm stuck at this point with the qemu-system-ppc64 install of FreeBSD.
I don't know about FreeBSD PPC64, however PPC32 appears to fail because OpenBIOS doesn't (yet) support the dma-* words required to map device memory. It doesn't look to be a particularly difficult task, however I'm not sure it's on anyone's radar at the moment. So I guess you'd have to either work on this yourself or try and bribe someone with beer tokens...
Andreas was the last person to work on PPC64, so he'd have a much better idea as to what the current situation is there.
ATB, Mark.
